Answer:

D

Explanation:

Physics and Chemistry are the most basic disciples in science, so the answer is not A or B.

Mathematics is the language of science; it could be the answer.

Most likely, you are looking for logic which describes the validity of an argument that has already been developed. I would pick D, but your marker may not agree.

Answer:

Δt = Δτ / (1 - β^2)1/2

Δt  is the time observed

Δτ is the proper time (3.00 s)

β = v / c = .96

Δt = 3.00 / (1 - .96^2)^1/2 = 10.7 sec

The velocity of the car will be   [tex]V=18.18\ \frac{m}{s}[/tex]

As velocity is the movement of the car with respect to time.

It is given that

Mass m  =  1100kg

Momentum= 22000 [tex]\frac{kgm}{s}[/tex]

The momentum is given as

[tex]P=mv[/tex]

[tex]v=\dfrac{p}{m}[/tex]

[tex]v=\dfrac{22000}{1100} =18.18 \ \dfrac{m}{s}[/tex]

Thus  the velocity of the car will be   [tex]V=18.18\ \frac{m}{s}[/tex]

Answer:

Explanation:

Situation 1 describes an elastic collision in which momentum is conserved while situation 2 is an inelastic collision in which momentum is not conserved.

When momentum is conserved, the speed of center of mass will not change. So the correct answer is Answer B: In situation 1, the center of mass never changes its speed, because there are no net external forces on the system before, during, or after the collision.

Answer:

A

Explanation:

Answer A: In situation 1, the center of mass never changes its speed, because block 1 is moving before the collision, and block 2 is moving after the collision.

In situation 1, the center of mass never changes its speed, because there are no net external forces on the system before, during, or after the collision.

Kinetic friction is related to the normal force N by f k = μ k N f k = μ k N ; thus, we can find the coefficient of kinetic friction if we can find the normal force on the skier

Explanation:

Answer: 0.75 Ohms

Explanation:

Use the Joule heating law stating that the power is equal to the square of the voltage over the resistance:

[tex]P=V^2/R[/tex]

Plug everything in:

[tex]48=(6^2)/R[/tex]

[tex]R=6^2/48[/tex]

[tex]R=36/48=0.75[/tex]

With a constant angular acceleration of 1.27 rad/s^2 and acceleration of 27.5 s, is mathematically given as

[tex]\theta = 1848 radians[/tex]

Generally, the angular velocity  is mathematically given as

w2 = 0 + 1.27*27.9

w2 = 35.43 rad/s

Therefore

[tex]\theta1 = 0.5*1.27*27.9*27.9[/tex]

[tex]\theta2 = w2*(66.1-27.9)\\\\\ \theta = \theta1 + \theta2[/tex]

[tex]\theta = 1848 radians[/tex]

In conclusion, the total angle is

[tex]\theta = 1848 radians[/tex]

Answer: x = 128°

180° - 52° = 128°

Answer:

128 degrees

Explanation:

A circle has a degree of 360, all around. You can imagine a circle, with the center being where the line intercepts the right angle.

360 = 52 + 38 + 142 + x

360 = 232 + x

The work done on the mouse by air resistance is equal to 196 Joules.

Given the following data:

Mass = 200 grams to kg = 0.2 kg.

Distance = 100 meters.

Scientific data:

Acceleration due to gravity = 9.8 [tex]m/s^2[/tex]

In Science, work done is generally calculated by multiplying force and the vertical distance or displacement experienced by an object.

Mathematically, work done is given by the formula:

[tex]Work\;done = force \times displacement = mgh[/tex]

Substituting the given parameters into the formula, we have;

[tex]Work\;done = 0.2 \times 9.8 \times 100[/tex]

Work done = 196 Joules.

The boy would lose 25000 Joules going from the top of the hill to the village.

Potential energy is the energy stored in an object as a result of its position in relative with another object. It is given by:

Potential energy = mass * acceleration due to gravity (g) * height.

g = 10 m/s²

Let us assume the boy has a weight of 50 kg. His starting point is (400, -50) m. This means the hill is 50 m high and 400 m from the village.

Potential energy = 50 * 10 * 50 = 25000 Joules

The boy would lose 25000 Joules going from the top of the hill to the village.
